It's never bad to be overcautious, especially when you can be harmed severely, or maybe even killed. That's why we give safety tests to students before they can use tools!

Just a fan will get you into dealing with all of the symptoms I listed earlier. To avoid a lot of discomfort you need a dedicated welding ventilation system and most likely a respirator for any residual fumes that get past the ventilation system.
